We have SpeedFusion between Peplink devices. And, we are routing with Cisco Router. Peplink is using OSPF. So, we create OSPF in the Cisco Router using the same area (0). But, In Cisco Route Table, the OSPF route of Peplink appears as O E2 route on Cisco Router. Why the O E2 route appears in Cisco Router when even we are using the same area between Peplink and Cisco?

Yes, the 0 E2 routes are appearing in Cisco Router. Peplink and Cisco are in the same area. So, they should not be O E2 route because they are in the same area. Am I right? Why they are appearing that?
